Letters Patent No. 93,169, dated August 3, 1869.

IMPROVEMENT IN WHIFFLETREES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concern:

Be it known that I, HENRY BUCK, of Chardon, in the county of Geauga, inthe State of Ohio, have invented a newa nd improved Whiiiletree.; and Ido hereby declare that the following is a full and exact descriptionthereof, reference being had to the accompanying. drawings, and to theletters of reference marked thereon.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

Figure l is a view of the whiiiietree, when in position before the hookis thrown out.

Figure 2 is a view of the whiiietree, when in the position to hookorunhook the tug.

rIhe drawings represent two forms of construction, (for whiliietreeswhen used in different situations,) one at each end.

' Letter A, iig. l, is the hook.

Letter B, iig. 1, is the band.

Letter f, fig. l, is the staple.

Hook A, band B, and staple f, as shown on the left-hand end oi" thedrawings, are intended for use when the whiletree is used in such a waythat it will turn or hang down when the tug is slacked.

Hook C, band D, and staple h, on the opposite end of the drawings, areintended for use in cases where the whiietree,while in use, is notpermitted to turnover, as, for instance, Where it is placed on tcp ofthecrossbar.

rlhe spring-latch J is not necessary, when the whiffietree is so usedthat it hangs down, when the tug is slacked. It is a device for holdingthe hook in position, by means of Ia notch on the point of hook C, byplacing hook C nnderstaple h and latch J, as shown on the right-handside of drawing,"h`igure 3, when the tug is slacked, and still be handyto hook or unhook.

The way the hook operates is this:

The tug. is attached when the hook is in the position as shown in g. 2,the end ofthe hook being then placed under the staple f, which stapleholds the hook in position, but the staple f is not material t0 its use.It can be used without itspresence, and when the tug slacks, thewhifdetree hangs down, or partially turns over, and the hook is thenkept in its place by means of the staple f.

In cases where the whiietree is hung in such a way to the cross-bar thatit does not turn and hang down when the tug is slacked, the hook is heldin position by means of the spring-latch J, staple h, as shown on theright-hand side of iig. 3, by letters C, h, and J.

In this form the staple h cannot be dispensed with.

What I deem as novel, is, the manner of constructing and applying hookA, band B, and staple. f, as shown in the drawings, and spring-latch J,or its equivalent, and staple h, which is necessary when a whiflletreeis attached to vehicles in the manner as described.

The improvement sought to be obtained is safety from unhitching of thetug, while in use, and durability and strength.

' What I claim as my improvement, and desire to secure by LettersPatent, is-
